PFAS in Saïx's tap water: 9 ng/L, 18x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
18× above our health benchmark
0.5 ng/L is our benchmark, not an official limit. Same EFSA method as Sweden, Denmark and the Netherlands, but stricter. It's a yearly average, compared here with the latest check.
Sample taken in Navès, on the same distribution network as Saïx (SYNDICAT SAIX NAVES). The health authority samples one tap per network; a network carries the same treated water everywhere.
More about this result
The US also limits PFOA and PFOS to 4 ng/L each, per substance.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).
More PFAS than in 95% of the cities we track

In Saïx, the 4 most closely watched PFAS (PFAS-4) add up to 9 ng/L (0.009 µg/L) at the latest PFAS check on 27 October 2025. That's 18 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 28 ng/L (0.028 µg/L), below the EU legal limit (100 ng/L). Sampled in Navès, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Saïx safe to drink?
Yes. At the check on 29 June 2026, the tap water in Saïx was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Saïx's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 28 ng/L. The EU limit is 100 ng/L, so this water is at 28 % of the limit. (below the EU limit)
Does the water in Saïx also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 9 ng/L. That is 2.3 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
How hard is the water in Saïx?
The water hardness in Saïx is 15.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.
Same water network
Same distribution network as Saïx, so in principle the same water.
